Verified Reviewer |Horrible product with no guarantee
I would never recommend Seal Master's product. After following the directions to seal my black top in the Fall, the product failed by Spring.
I've used many other products and they have lasted pretty well. I was assured by this company's employees that their product would last longer than big box store brands.
After much communication, they refused to replace nor refund any of the product nor money I spent. They don't stand behind their product for the DIY home-owner.
To me, this justified the fact that their product costs more (e.g., $40 for a 5-gallon bucket and a crack filler for $26). I asked for specific directions/recommendations on how to apply the product and how much I would need. I purchased five 5-gallon buckets along with a crack filler. I meticulously followed all directions and carefully applied it in the fall.
I only use a snow blower, and after winter, I noticed how poorly it held up; see the attached picture. After dozens of emails and texts and even stopping by the shop, they decided that they would not stand behind their product. I was even told by John, the sales rep, that they would guarantee a company/corporate seal job but not a private DIYer's homeowner's job! This has been the biggest waste of money, the poorest quality product, and the lack of concern for a satisfied customer that I have ever experienced.
I would not recommend my worst enemy buy and use their products.
I'm super disappointed that I couldn't rely on and trust a local business. I'm off to the local big box stores to buy driveway sealant from now on, but now I'm over $240 poorer because of SealMaster in Buffalo, NY!
- Local comapany
- High price
- Low quality
- Poor longevity
Preferred solution: Full refund
User's recommendation: Do not use SealMaster Products!

Verified ReviewerI do not recommend stealmasters sealing
I dont recommend Stealmasters
for several reasons. Taran, the owner, is quick to respond to you at first as a potential client, but after doing business with him, hes too busy to answer any phone calls or texts in an appropriate time frame.
After the sealing was complete, the streaks never went away. That I could accept. One week later, white streaks were showing, as my neighbour noticed. Taran, the owner, responded that it was embarrassing and he would reschedule for another coat.
The rescheduling never happened as he was complaining it wasnt worth his time and the gas money involved. I, being rational and gracious stated that I would cover the gas costs. It wasnt enough. I gave him so many opportunities to fix this and he didnt care.
Save your money and find a professional company. In addition, the exact sealer they use can be purchased at Home Depot for 26 dollars for a large can.

Verified ReviewerThey Don't Deliver What they Say! Not as Advertised.
An assistant visited from a neighbor's property, asking if I wanted my driveway done. I asked what the service was and the price.
The owner of United Contracting, Donny Costello, returned with 2 pieces of literature re: SealMaster Coal Tar Pavement Sealer to read. I was able to make a copy. I asked what the price was and then followed with what a cash price would be which was quoted lower. Having a need to resurface our driveway, I immediately discussed with my husband and gave him the go ahead.
SealMaster Coal Tar was originally applied 9.27.22.
Later that day, it was not to my satisfaction; so owner, Donny Costello, asked me to send pictures of what I was not satisfied with. I sent 8-10 pictures, via text, of white tips showing through the black sealant and he said he would reapply a "flashcoat".
THREE FOLLOW-UP APPOINTMENTS WERE MADE & BROKEN!
- 10-10-22 appointment was between noon and 1 PM. Donny was a NO SHOW! He then rescheduled the next day.
- 10-11-22 appointment was between 1 and 2 PM.
Again, that didn't happen! Again, scheduled the next day
- 10-12-22 appointment was no specific time. Each time I asked when he would be arriving and he simply just scheduled for the following day. On the third day I was asked for our address.
That was promptly sent at 1:06 PM via text. No response and NO SHOW, again. I asked why. Donny said he never got the address that was texted.
He asked for a Screenshot of that message. I have never had my integrity questioned! I followed with 3 screen shots, which he finally said he received one.
Although he was "nearby" today and we had an all day appointment, he never visited.
I had blown the leaves and debris off the driveway on Monday, fully expecting his arrival that day, the following day and again today. None of the 3 appointments were kept!
- 3 broken appointments the lack of product applied
Preferred solution: A second application as promised.
User's recommendation: Pay with a check or credit card so you could cancel payment or originate a billing dispute if dissatisfied or service was not as expected.

Verified ReviewerResolved: Disappointed the cracks were not filled better so water would not get down, freeze and expand.
They came out and applied a 2nd coat, called a "flash coat".
Preferred solution: Return to overspray a second time as the brochure explains!
User's recommendation: Ask questions and request another spray or manual spreading.
Bad job
I made an appointment with Geno Gillette but on the day of the appt, rain was forecast and I told him not to do the drive. He insisted that it would be dry before it rained and the job was guaranteed and he started working on it anyway.
He finished before the rain but 5 minutes after he left, the rain came down. Spots opened up and sand came out.
I called but the number was out of service. I e-mailed but got no response. This was a long time ago(2013) but I haven't forgotten it.
I was busy caring for my ailing spouse so never filed a lawsuit. If I ever run into Mr.
George or Gillette, I will take great pleasure in telling them what I think of them. What goes around, comes around.

Verified ReviewerBad Company
My husband and I bought material from them and we use it on a parking lot. The material had something in it that burned us really bad.
We use protective glasses and protective clothing. My husbands eyes are really bad hes about blind in one eye.
I had 2 degree burns to my face and neck which I have scaring from now.
The owner will not do anything about this. The insurance company that they have says there not responable for our injuries.
We have obtained an attorney on this.
Pattern concrete sealing Totonto, The Seal Master
Sealmaster has two numbers one for Vaughn and one for Mississauga.
In their quote they mentioned that they put two coats of selaent and that it restores the look of the concrete.
I called them to seal my concrete driveway, they came and did the sealing but on the day itself I was suspecious whether the second coat was put or not. A week later sealent is washed out in several places and I can see several dry spots on the driveway. I called them to take a look at the issue and not only do they refuse to come and see the issue insisting that the job was done properly but Cam(name of the person I spoke to) also hung up on me.
Be warned if you think you can trust this companys claims. The advertising is misleading, the attitude when you speak to them leaves a bad taste and the work shoddy.

I would like to update the follow up from SealMaster and Donny Costello. He finally sprayed the second coat today, as stated he would do days ago.
My original rating yielded 1.2; since he finally provided a second coat, I would like to raise that to a 3. A lot of frustration but Donny finally did as he stated he would do.
